Overview
The CNC140C-2 double spindle and double carriage CNC thread turning machine has a double spindle and double carriage structure, which can simultaneously turn two couplings. The size of the processing coupling is 2-3 / 8 "～ 5-1 / 2 ", the bed is inclined structure, the machine tool spindle chuck uses hydraulic power chuck, the spindle bearings are ZWZ, HRB, NSK and other well-known domestic brands and imported brands, the tool holder at each spindle is a two-station fixed row knife Frame, the spindle motor adopts explosion-proof asynchronous motor or main servo motor, the numerical control system is FANUC numerical control system, and automatic chip removal machine can be optional.
This machine tool is a special numerical control equipment for processing the special threads of petroleum oil casing coupling threads and special threads of petroleum oil casing couplings. It can also be used as a general numerical control machine tool. Cone, sphere, curved surface and cuts. Large application range, high efficiency, good accuracy and stability, good part size uniformity, easy to operate.
